after a part number that converts the b310 lca arm to the 120y pitman ?knuckle arm

have a set on a 120y s/w i have here i want to replace the 120y ones wont fit the b310 arms and the b310 ones wont tighten up enough due to the shaft being to big and i dont want to drill the knuckle arm out any thought

As per my PM,
There isn't to my knowledge a ball joint that does this. All the Lower ball joints with the 10mm holes, have the larger taper. So the best fix is to find some 1200 ute steering arms, which will fit the 1200/120y struts, but have the larger taper too.
